Title: Low power oscillator
Inventor: KAWAMURA J PATRICK
IPC: H03K19/0185
Filed: 2006-07-18
Abstract: <P>PROBLEM TO BE SOLVED: To reduce power consumption of an oscillator circuit while maintaining efficiency of a pump circuit in the oscillator circuit including the pump circuit.  <P>SOLUTION: An oscillator circuit (150) is designed with a reference circuit (102), responsive to a first voltage, for producing a second voltage. An oscillator (108), responsive to the second voltage, produces a first output signal having a magnitude less than a magnitude of the first voltage. A level translator (114), responsive to the first output signal, produces a second output signal having a magnitude greater than the magnitude of the first output signal. Since the oscillator produces the first output signal with a magnitude less than the magnitude of the first voltage, power consumption is reduced with respect to an oscillator operating at the first voltage. The magnitude of the first output signal is increased by the level translator to a desired magnitude of the second output signal.  <P>COPYRIGHT: (C)2007,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To improve the current driving capacity to a boosting capacitor without increasing a footprint as a device, in a charge pump type voltage booster circuit.  <P>SOLUTION: In the charge period of a capacitor C1, a PMOS transistor Q1 and an NMOS transistor Q2 are turned on, and the capacitor C1 is charged with electricity by the voltage between potential VCC and potential VSS. On the other hand, in the discharge period of the boosting capacitor, the PMOS transistor Q3 and the PMOS transistor Q4 are turned on, and the charge accumulated in the boosting capacitor is discharged. In the discharge period of the capacitor C1, a selector SEL1 selects a terminal T1, and a feedback system is formed, where the operation voltage applied to the gate of the PMOS transistor Q3 changes according to the fluctuation of output voltage VDD2. At that time, only the resistance components of the PMOS transistor Q3 exists and a differential amplifier does not exist on the path (between the potential VCC and the low-voltage-side terminal C1N of the boosting capacitor) of the current flowing into the capacitor C1.  <P>COPYRIGHT: (C)2008,JPO&INPIT
